Lively has joined the Phillies in Washington D.C., and he will serve as the 26th player for Sunday's doubleheader, Meghan Montemurro of The News Journal reports.
The right-hander will serve as depth for the twin bill. Lively owns a 2.48 ERA in 36.1 innings for Triple-A Lehigh Valley this year, striking out 24 and walking five. Lively delivered for the IronPigs with an 11-5 record and a 3.06 ERA last season, as well. Despite that success, he's lost steam as a prospect.
